SVChost.exe - k netsvcs has crippled my machine like no malwaer ever has. From what I can tell, this has something to do with Windows Update.
Nothing else unsual is running. There is no malware involved. And all updaes are installed Except I cannot update .net. I get the following error message:
"Microsoft .NET Framework 3.5 Service Pack 1 and .NET Framework 3.5 Family Update for .NET versions 2.0 through 3.5 (KB951847) x86"
What can I do? I am frustrated.

Thanks for the help! I followed Joel's advise above & it SEEMS to have resolved the problem. I say SEEMS, because I have seen the problem apparently resolved, only to resume again after a few days. Updated Malwarebytes showed no infection doing a deep scan.
I will be back if proble returns.... for now, issue resolved!
I too hace a problem with svchost consuming excess memory (and CPU). I tried every thing, including nightly super/deep anti-virus scans with Checkpoint ZoneAlarm (uopdated nightly as well) Malwarebytes' Anit-malware, Anitsuperspyware and Microsofts MSRT but the problem persisted.
I tried to isolate the problem with the Process Explorer, tried to shut down individualt processes to further isolate and nothing helped. Shutting down svchost and restarting the individual subprocesses (audio, RPC, etc.) provided some temporary relief but withing a few hours, the svchost process was consuming 50% (500MB) of RAM.
Last week I tried the MSRT from MS (version 3.9.3901.0) and it found and 'partially' remove a virus call Alureon. MSRT recommended another full scan by anit-virus software so I ran another deep scan of ZoneAlarm Anti-virus.
Evidently the combination of the two worked! Since then the largest svchost.exe process has used only about 25MB RAM and the 'puter has been on and in use for 5 consecutive days.
The Alureon rootkit can me hard to get rid of. I have found two scanners which seem to remove it. TDSS Killer and HitmanPro.

The "Process Explorer" technique can potentially be used to get more information about what service in the netsvcs instance of svchost is responsible for the CPU consumption. Once that detail in known, more specific steps can be taken to attempt to address the problem. Another option would be to use Process Explorer to selectively stop services that are running in the netsvcs instance of svchost. If you stop a service, and the CPU usage immediately goes down, you can focus efforts on that service and why it may be contributing to the behavior.
